1. A method of processing a slurry containing organic components and water, comprising:
in a reducing step, reducing a percentage of water of the slurry to form an intermediate composition;
in a mixing step, transporting the intermediate composition to a mixer and increasing the water content by mixing the intermediate composition with a hot process water to form a ready mix;
increasing pressure and temperature of the ready mix to bring the water in the ready mix to a supercritical state;
transporting the ready mix via a heat exchanger to a reactor;
in a converting step in the reactor, converting through supercritical water gasification at least a part of the organic components in the ready mix to hydrogen and one or more hydrocarbons to produce a converted slurry;
separating solids from the converted slurry into separated water and solids;
recycling at least some of the separated water from the converted slurry as a heat exchanging counter current via said heat exchanger to a gas-liquid gas-liquid separator to separate the hydrogen and hydrocarbons;
recycling at least some of the separated water as the hot process water in the mixing step, so as to recycles heat used in the converting step.
